I could successfully install the Ample Percussion Cloudrum library on my external SSD which is formatted in APFS. It's also running in Logic. But when I'm trying to install Ample Guitar M Lite library on the same drive, the drive is appearing in the Finder but in inactive state and so, it is not allowing me to choose the destination folder on that external SSD. What could be the reason? Please suggest me a fix.

My Mac is running macOS Tahoe 26.7.1.
